System-wide learning from root cause analysis: a report from the New South Wales Root Cause Analysis Review Committee

Abstract

Background Preventable errors are common in healthcare. Over the last decade, Root Cause Analysis (RCA) has become a key tool for healthcare services to investigate adverse events and try to prevent them from happening again. The purpose of this paper is to highlight the work of the New South Wales (NSW) RCA Review Committee. The benefits of correctly classifying, aggregating and disseminating RCA data to clinicians will be discussed. In NSW, we perform an average of 500 RCAs per year. It is estimated that each RCA takes between 20 and 90 h to perform. In 2007, the NSW Clinical Excellence Commission (CEC) and the Quality and Safety Branch at the Department of Health constituted an RCA review committee. 445 RCAs were reviewed by the committee in 14 months. 41 RCAs were related to errors in managing acute coronary syndrome. Results and discussion The large number of RCAs has enabled the committee to identify emerging themes and to aggregate the information about underlying human (staff), patient and system factors. The committee has developed a taxonomy based on previous work done within health and aviation and assesses each RCA against this set of criteria. The effectiveness of recommendations made by RCA teams requires further review. There has been conjecture that staff do not feel empowered to articulate root causes which are beyond the capacity of the local service to address. Conclusion Given the number of hours per RCA, it seems a shame that the final output of the process may not in fact achieve the desired patient safety improvements.

Use of the Generating Options for Active Risk Control (GO-ARC) Technique can lead to more robust risk control options

“…Healthcare organizations in many countries have adopted operational risk management tools such as root cause analysis (RCA) [1][2][3][4][5], failure mode and effects analysis (FMEA) [6][7][8], and -to a lesser extentother such techniques [8][9][10][11][12] to address the systems-level determinants of patient safety. One key feature…”

Analysis of risk of medical errors using structural-equation modelling: a 6-month prospective cohort study

“…Many medical facilities have implemented incident-reporting systems to prevent such errors, and details regarding causes of near misses and adverse events are now determined using a root cause analysis (RCA) 5 6. RCA aims to determine not only the types of mistakes made but also the root cause of near misses and adverse events, thereby facilitating improvements in an organisation's activities and preventing reoccurrence of similar events.…”

The Causes of Their Death Appear (Unto Our Shame Perpetual): Why Root Cause Analysis Is Not the Best Model for Error Investigation in Mental Health Services

“…8,9 The RCA model is applied across NSW Health to all types of accidents and errors in health care. 10 Anecdotal evidence suggests that the model is not well suited to mental health services, particularly in reviews of suicides and homicides (which account for 90% of all SAC 1 events). The problem is that such incidents do not lend themselves well to identification of a root cause.…”
